Christa joins a tour group heading deep into the snowy expanse of the Rocky Mountains, but when a bitterly cold snowstorm sweeps the region, the small group is forced to take shelter in an abandoned hunting cabin. Terrified, and completely isolated by the storm, Christa finds herself trapped with eight total strangers. One of them kills for sport...and they're far from finished. As the storm grows more dangerous and the number of survivors dwindles one by one, Christa must decide who she can trust before this frozen mountain becomes her tomb.
